GEORGE CAWLEY, OF WESTMINSTER, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 708,462 dated September2, 1902. Application filed June 3, 1902. Serial No. 110,120. (No model.)

" To aZZ whom it may concern:

Be it known that I, GEORGE CAWLEY, civil and mechanical engineer, asubject of the King of Great Britain and Ireland, residing at 29 GreatGeorge street, in the city of Westminster,England,have invented acertain new and useful Vehicle to be Used in Electric Traction onRailways; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to provide a vehicle in which electricalenergy is utilized to great advantage for electric traction on railways,superseding the use of ordinary steam-locomotives and the use of fixedelectric generating-stations and conductors as ordinarily used inelectric railways,and the weight to be equally distributed over eachpair of running-wheels in a manner which cannot be done withsteam-locomotives. With this object I provide a framing supported uponbogies in such a manner that the width of the framing is not restrictedby the wheels, as in ordinary locomotives, but can be extended to orbeyond the vertical plane in which the bogie-wheels are situated, and Ithus provide a base upon which I can mount-a boiler or boilerssufficiently powerful to operate engines, which in turn actuate dynamosby which electric current is generated upon the vehicle itself, and thesaid current is employed to actuate motors on or connected with all orany desired number of the axles of the wheels of the bogies and also, ifrequired, to the axles of the wheels of other vehicles connected withthe said vehicle. The said framing also carries water-tanks,fuel-bunkers, and the regulating and measuring appliances necessary forcontrolling the apparatus and the current generated by it.

The accompanying drawings represent in side elevation in Figure 1 and inplan in Fig. 2 a vehicle constructed in accordance with my invention.

A is the framing carried by the two bogies B, each bogie being providedin the arrange ment shown with three pairs of wheels. The framing Aextends to or beyond the vertical plane in which the wheels are situatedand is thus wide enough to support a boiler (indicated at O)sufficiently powerful to supply enough steam to operate engines foractuating dynamos for generating a powerful electric current. Theseengines and dynamos are indicated at D.

E represents fuel-bunkers, and F represents water-tanks above and belowthe boiler and underneath the frame.

The whole of the parts described are inclosed by a body part or casingwith windows therein to admit light to the interior, this being arrangedso as to include cabs G at each end of the vehicle and passages H alongthe sides of the boiler and between the fuelbunkers E and through theengine-room, so that the attendant can pass from one cab to the other.

The arrangement described constitutes a locomotive electric generatingplant, which can be itself propelled by the electric energy generatedthereon, and this electric energy so generated can be supplied to theaxles of the Wheels of carriages or trucks attached to the said vehicleand can also be employed for other purposes required-such as forlighting the train, operating the brakes and the like for supplyinglight or power in the neighborhood of the vehicle.

By my invention I can employ electric traction on railways withouthaving to supply it through long conductors or rails, as is necessarywhen electric current is supplied to the vehicles from stationarygenerating-stations in the ordinary way;

By the use of the vehicle according to my invention, constituting whatmay be termed a traveling electric generating-station, I obtain greatereconomy in the current generated, as I do away with the resistance andleakage due to the use of long conductors.

I claim as my invention- 1. An electric vehicle, having asupportingbogie at each end thereof and carrying a boiler, water-tanksabove and below the boiler, and fuel-bunkers at one end of the boilerwith en gines and dynamos on the other side of the fuel-bunkers,substantially as described.

2. An electric vehicle, havingasupportingbogie at each end thereof andcarrying a boiler, water-tanks above and below the boiler, and

fuel-bunkers at one end of the boiler with enroom and then to the othercab, substantially gines and dynamos on the other side of the asdescribed. 10 fuel-bunkers, in combination With a cab at In testimonywhereof I affix my signature each end of the vehicle and passages withinin presence of two Witnesses.
